- MW, molecular weights in kilodaltons; SCO, subcommissural organ; RF, Reissner's fiber; AFRU, antibody against all glycoproteins of bovine RF; Con A, concanavalin A (affinity = mannose, glucose); WGA, wheat germ agglutinin (affinity = glucosamine, sialic acid); +, positive reaction consistently present in all samples; *, positive reaction only found in some samples. Two upper boxes indicate putative precursor forms only present in SCO. Lower box indicates the only compound consistently found in SCO, RF and CSF (processed form).
